Atlantic Lodge is in White Cross, Cornwal. It's one of a row of holiday villas. There's a shared lawn out front, but you get your own private seating area. It's simple and clean.
It sleeps four. Two bedrooms, one with a double bed and one with two singles. One bathroom. The stairs are fine.
The living room is a decent size, and it's open-plan into the kitchen and dining area. It's got what you need. There's a washing machine, wifi, and parking right outside. You can bring one dog.
You're about six miles from the coast. Newquay is the main town, with all the beaches like Fistral and Watergate Bay. It's good for surfing. The town has the zoo and the aquarium if the weather turns.
Padstow is about a twenty-minute drive. Nice harbour, good for wandering and getting something to eat. Port Isaac, where they film Doc Martin, is a bit further on. If you like walking, the Camel Trail is good for bikes or a flat stroll. It goes from Wadebridge to Padstow.
You can't use the leisure facilities on the park, but there's a cafe and a pub you can go to. There are water parks nearby if you've got children.
